Appiication ined any i7,

To all whom t may concern.'

Be it known that I, DlivILi-i S. DU BRUL,a citizen of the United States, and resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in a Matrix, of which the following is a specification.

The present invention relates to a. matrix or mold which is designed primarily for used with cigar bunching machines, and is an improvement on the matrix set forth iii the patent to F. C. Hiller, No. 567,350 of September S, 1896. Y

As heretofore practised, matrices of the character described have usually been made with their side walls adjustable to effect an increase or decrease in the area of Athe matrix opening, Vwhich would result in changing the shape of the mold and increasing or decreasing the size of the lobject t-o be molded. It has been found that, while a proportional adj ust-ment, which was mechanically very good, could be obtained with the matrices now employed, the tobacco did not run into these matrices iii proportion to the shape of the opening. Consequently, the present design has been appropriated to give a plurality of independent adjustments at different points in one side wall of the mold opening, and to provide these adjustments by constructing the said wall of the mold of a plurality of sections,

and having these sections wide enough to cover considerably more of the length of the cigar to be molded on each section than did the separate tumblers on the previous construction.

Another object of the invention is to so construct the matrix, particularly thek ad.- justing means, whereby a wider range is obtained, enabling a. number of shapes to be had with the same matrix. Y

While the device contemplated by the invention will be hereinafter described as especially adapted for cigar bunching machines, it should in no way be construed as limited to this particular use, as it may readily find expression in a matrix which may be used to advantage in other co-related arts. Futliermore, while the matrix in its preferred form consists in constructing one side wall of the matrix opening with a plurality of independently adjustable sections, it is to be understood that the opposite side wall in some instances, should 1919.

conditions require it, can be also constructed with like sections. f' Y Referring to the accompanying drawing, which ilnstrates the preferred features of the invention, the figure is a perspective view of the matrix constructed in accordance with the invention. i

:Brepresents the frame, which is of a size to conveniently adapt it to power bunching machines. vThel matrix opening 6 `is fopen throughout the depth ofthe frame 5' and is formed in the frame 5 by means of the rigid l.side wall 7 and the opposite side wall', which is composed of a plurality of independently adjustable sections comprising the blocks 8. Overlying the rigid side wall 7 is a metal plate 9, which is preferably of tool steel and acts in conjunction with'a similar plate at i the bottom of the'hopper under which the matrix slides. These two plates act to shear off the tobacco as the matrix leaves the machines, as is cfommonin cigar bunching machines. Underlying the Vframe 5` is a metal plate lO, which extendsv partially across the bottom of the matrix, thereby providing a smooth, even bearing surface for the blocks 8. Each of the blocks 8 is provided on its under side with a recessed portion 1l, in which is receivedv the metal strip 12, which stripvlimits the amount of adjustment ofthe blocks. Carried by the their ende vby turning the screw clockwise, its screw- Vthreaded engagement with the block would Vframe 5v is a bar 13, which extends longicomprising elongated, set screwsl tend to draw the same away fromftlie matrix Y opening, thus vvarying the area of the opening at this particular point; by turning the screw anti-clockwise it would tend to push j the block toward the opening, resulting in decreasing thev area of the openingat thisV particular point. Y

As is commonin cigar bunching machines, the Vmatrix is shiftable to .tw-o positions, in

ilo

one position it forms a section of the hopper and is located above the flat bottom plate and While in this position has pressed down into it 'from the upper part of the hopper the desired quantity of ller. lt is then shifted to the second position oill of the bottom plate thereby leaving the bottom ot' the matrix open above the rolling apron and in this position a plunger presses the tobacco down through the open bottomed matrix onto the rolling apron. After having been acted upon by the rollingapron in the usual manner, the cigar bunch is carried therefrom by mea-ns of jaws, and deposited through these aus with the aid of another plunger into the mold. In the movement from the Erst to the second position which takes place usually in a. direction` normal to the longitudiiml axis of the matrix, the tobacco in the matrix is sheared oit the tobacco column in the hopper by the knife edge (shown at 9 in the drawing) actingin conjunction with a similar knife edge at the bottom of the hopper proper thus deterniining the amount ot' tobacco which goes into the matrix and therefrom to the rolling apron.
